80% of Prostate Supplements Contain Fraudulent Saw Palmetto
Nearly 40 million men in the United States over age 40 experience age-related changes in prostate health. Most turn to supplements for support. Most get ripped off.
Here's why: 80% of each saw palmetto harvest gets shipped to Europe, where doctors prescribe it as a first-line pharmaceutical aid for prostate issues. This creates a supply crisis in U.S. markets. To compensate, manufacturers spike their formulas with vegetable oils—olive oil, sunflower oil, any cheap, unnecessary filler that looks similar—and hope you don't notice.
The result: ineffective formulas that can't deliver clinical results because they don't contain real saw palmetto.
At Smarter Reviews, we analyzed numerous prostate supplements against U.S. Pharmacopeia verification standards and only a select few had authentic USP Saw Palmetto. Read on to find out which formula is best rated.
4 Ways A Quality Prostate Supplement Can Benefit Quality of Life
The size of your prostate as you age determines the frequency of your urination issues. A high quality prostate supplement addresses your prostate size from various angles like nutrition, oxidative stress, and hormones.
Many men with aging prostates have to wake up multiple times per night to use the bathroom. This can mean poorer quality sleep, which takes a toll on almost every aspect of our lives. A good prostate supplement can help decrease this urge to urinate and limit the number of times you need to wake up.
An aging prostate can mean more times having to urinate, but also a weaker, less controllable stream. Sometimes urgency becomes less noticeable, and leakage can result. A quality prostate supplement can help maintain urinary sensitivity, strengthen your stream, and better control when you urinate.
Frequent urges to urinate often put limitations on what we can do, like trips in the car, sports games, meetings at work, and dinners with family. An effective prostate supplement can lengthen the time spent between bathroom trips by supporting better bladder emptying, improved comfort, and reduced urgency.
Being romantic can be difficult when dealing with an aging prostate. A quality prostate supplement can help you maintain a healthy libido and enjoy more confidence in the bedroom.
Why Saw Palmetto Fraud Is Rampant—And How to Verify Real Saw Palmetto
Saw palmetto grows exclusively in Florida and is harvested once annually during an 8-week window when berries reach peak potency. European pharmaceutical companies purchase 80% of each harvest because saw palmetto extract is an approved prescription drug for prostate issues in Germany, France, and Italy.
When demand exceeds supply, adulteration becomes profitable. Manufacturers mix cheap vegetable oils with minimal saw palmetto, use year-round harvested berries (60% lower active compounds), and skip proper CO₂ extraction for cheaper chemical solvents. Without verification, consumers can't tell the difference.
One of the ways to verify authenticity: Check for USP-verified labels on saw palmetto supplements—they match fatty acid profiles from authentic Florida harvests to confirm purity and potency, like a quality seal.—similar to how law enforcement matches fingerprints to verify identity. Only one saw palmetto supplier has passed USP's Dietary Ingredient Verification Program (DIVP): USPlus® by Valensa International. Any formula claiming "saw palmetto extract" without USP verification is unverifiable. You're trusting the manufacturer's word against a documented history of widespread adulteration.

Why European Doctors Prescribe Saw Palmetto (And U.S. Doctors Don't)
In Germany, France, and Italy, saw palmetto is prescribed as a first-line aid for prostate issues because clinical trials show 320mg saw palmetto CO₂ extract performing effectively for prostate health. However, U.S. doctors don't prescribe it because it's classified as a supplement, not a drug. Pharmaceutical companies often avoid pursuing FDA approval for naturally-sourced extracts due to high costs and limited clinical evidence, cutting their profit potential.
The result: European men get high quality saw palmetto through doctors. Americans navigate an unregulated market filled with substandard products.
The key difference: European pharmaceutical saw palmetto is verified, standardized, and dosed at 320mg CO₂ extract. U.S. supplements rarely meet these standards.
The exception: Among tested saw palmetto formulas, few deliver USP-verified, 320mg CO₂ extract that matches European pharmaceutical standards.
Key Ingredients for Effective Prostate Support
USPlus® Saw Palmetto — 320mg
Mechanism: Targets 5α-reductase + alpha-adrenoceptor
Verification Standard: USP DIVP certification required
Beta-sitosterol — 180mg+
Mechanism: Regulates healthy prostate size, urinary flow support
Verification Standard: Complex blend (not isolate)
Pumpkin Seed Oil — 260mg
Mechanism: Lowers oxidative stress, targets DHT levels
Verification Standard: Combined with saw palmetto
Boron — 3mg
Mechanism: Supports PSA binding
Verification Standard: Chelated form preferred
Supporting Ingredients for Men
Lycopene (10mg): Antioxidant support
Lutein (6mg): Overall cellular health

Vitamin D3 (2000 IU): Immune support
Why 320mg Specifically?
Clinical trials demonstrating efficacy used 320mg doses. This matches the European pharmaceutical standard.
What Causes Prostate Symptoms and What Helps
Too Much Testosterone Converting to DHT
An enzyme with strong activity converts testosterone into DHT—a more powerful hormone that influences prostate size and urinary flow, which may contribute to a weak stream and nighttime bathroom trips.
What helps it: 5α-reductase targeters like USPlus® Saw Palmetto (320mg), Pumpkin Seed Oil (260mg), and Beta-sitosterol (180mg+)
Muscle Tension Around Your Urethra
Tension may cause muscle receptors to tighten around your urethra, making it hard to start urinating and causing urgent trips to the toilet.
What helps it: Alpha-adrenoceptor targeters like USPlus® Saw Palmetto (the only ingredient clinically studied to support healthy DHT levels and a normal urinary flow)
Cell Overgrowth Around the Prostate
An enzyme called PSA drives hormone activity that multiplies cells around your prostate, which might add external pressure to your urethra.
What helps it: PSA targeters like Boron (3mg)
3 Features You Must Avoid
The market is filled with so-called "prostate fixes" that include a wide array of herbs and botanicals. However many of these formulas lack the recommendation of a board-certified doctor who understands the importance of proper ingredient selection and dosing.
What's worse, many of these botanicals may contain unstudied chemicals that can have unknown long-term effects. That's why we suggest only ever choosing a prostate supplement that has been specifically formulated by a medical professional.
The studies behind saw palmetto are hugely promising, though sourcing this botanical has proven challenging. Because it's notoriously in short supply, an unfortunate trend of fake saw palmetto has become prevalent. In fact, the only true way to ensure there is real saw palmetto in your supplement is if its verified by the non-profit United States Pharmacopeia (USP). That's why we suggest only choosing a supplement that contains USP-verified USPlus® Saw Palmetto.
This cheap filler is used to help bind ingredients together and lubricate the supplement so it doesn’t gum up when it is run through the manufacturing machines. Magnesium stearate adds no nutritional value and can become toxic to your system.

Learn More3. Prostate Advanced
7/10
B+
Overall Grade
PROS
- Contains saw palmetto and beta-sitosterol
- Includes lycopene (from LycoBeads®)
- Contains Flowens™ cranberry extract (clinically shown to improve International Prostate Symptom Score by 25%)
- Contains boron
CONS

- No USPlus® verification (saw palmetto authenticity unconfirmed)
- Requires 3 tablets/day
- No lycopene
- Individual ingredient doses concealed behind proprietary blends
The Bottom Line
Force Factor Prostate Advanced includes all the right ingredients—saw palmetto, beta-sitosterol, pumpkin seed, lycopene, and boron. The problem is dosing transparency. The saw palmetto lacks USP verification (authenticity unconfirmed given the fraud problem), and the 629mg proprietary blend makes it impossible to verify if saw palmetto reaches the 320mg clinical threshold or if boron reaches the 3mg target.
